Semtech Corporation GS2993
Dual Output Adaptive Cable Equalizer
FEATURES
● SMPTE 424M, SMPTE 292M and SMPTE 259M compliant● Automatic cable equalization
● Multi-standard operation from 143Mb/s to 2.97Gb/s
● Performance optimized for 270Mb/s, 1.485Gb/s and 2.97Gb/s. Typical equalized length of Belden 1694A cable: 140m at 2.97Gb/s 220m at 1.485Gb/s 400m at 270Mb/s
● Supports DVB-ASI at 270Mb/s
● Dual, independently-controlled outputs
● Manual bypass (useful for low data rates with slow rise/fall times)
● Programmable carrier detect with squelch threshold adjustment
● Automatic power-down on loss of signal Standby power <30mW (typical)
● Differential outputs support DC coupling to 1.2V, 2.5V or 3.3V CML logic
● 0/6 dB gain boost selection pin
● Cable Length Indicator output; varies monotonically with input cable length
● Selectable de-emphasis: 2dB, 4dB and 6dB
● Standard EIA/JEDEC logic control and status signal levels
● Single 3.3V power supply operation
● 207mW power consumption (typical)
● Wide operating temperature range of -40ºC to +85º...
